A male or female who dresses up like a fictional character from any pop-culturally relevant medium such as a manga or anime series, comic books, movies, videogames, etc... and makes money from doing so.

One who dresses up like a character at Comic-Con and charges money for a photo would be cosidered a Cospimp. Though they may also be referred to as a "Cosdouche".

The ultimate Cospimp would be Christian Bale or Robert Downey Jr.

'A lot of people "Cosplay" as Wolverine, and that's cool. But I "COSPIMP", as Wolverine.' ~ Hugh Jackman*
